A Safety Approach for Improving Security - Effective Coordination Strategies at the Airport Security Screening Checkpoint.

Abstract

This study aimed to analyze effective teamwork at security checkpoints by investigating how security crews communicate in different (routine and threat) situations. Working at an airport security screening checkpoint is challenging. Although tasks and processes are highly regulated and standardized due to legal requirements, security screeners must be trained to deal with unforeseen threat situations involving high levels of uncertainty. Therefore, security crews need to engage in flexible and adaptive coordination according to the situation and circumstances. We conducted a field study with 20 airport security screening crews comprising 100 security screeners. Teamwork in terms of interaction between crew members was measured, differentiating between proactive "push" communication and information on request representing "pull" communication. Furthermore, non-task related communication was assessed. While crews showed non-task related communication more in routine situations, both task-related "push" and "pull" communication occurred more in threat situations. In terms of team performance, we could show significant positive effects of proactive "push" communication and non-task related interaction in threat situations. Our results underscore the specific setting of airport security screening and the challenges that arise for teamwork. This study investigates professional screeners and passengers in the field. In contrast to other high-risk areas, security crews are confronted with a third party that complicates coordination strategies considered effective in previous studies. Our findings recommend situation-specific communication strategies for practical training for airport security screening crews.
